[Samba] Samba 3.0.0 compile errors

[Julian C H Stevens]

Apologies first!
I am currently maintaining a very old SunOS 4.1.3_U1 server which is in a
sensitive location an cannot be upgraded.  It will be replaced soon, but in the
meantime...
I need to upgrade my Samba 2.0.6 to Samba 3.0.0, but receive the following
compile errors:

Can anyone tell me if the warnings are significant, and what the parse error
indicates?
Thanks.
